Duet-Wifi + Duex2 - short-to-ground reported by driver(s) 7 8 9

[CR3D]

Hi Community,

i have a strange problem. With a standard setting of mine with a duet wifi and DUEX 2, I get the error message:

Error: short-to-ground reported by driver (s) 7 8 9
Error: over temperature shutdown reported by driver (s) 7 8 9

but since it is a DUEX 2, these drivers are not available.
How can this error message come about?

The firmware is also stable at 2.05.1

here the wiring:

The Duex is also supplied with 24V.

The Setup works normally, everything works! There ist just the error-message...

Thank you in advance

post your config

also does your wire conform with ?

Yes you can see the double wire clamp at the duet wifi...

here the config:
Notice, this config works identically at other printers too ...

try adding

M569 P7 R-1
M569 P8 R-1
M569 P9 R-1

however i would suggest that you update to 3.1.1

M350 X16 Y16:16 Z16:16:16 E16 I1 ; Configure microstepping with interpolation

M92 X80 Y80:80 Z1600:1600:1600 E409 ; Set steps per mm

M566 X400 Y400:400 Z50:50:50 E500 ; Set maximum instantaneous speed changes (mm/min)

M203 X50000 Y50000:50000 Z800:800:800 E12000; Set maximum speeds (mm/min)

M201 X900 Y900:900 Z1000:1000:1000 E1200; Set accelerations (mm/s^2)

you can only define multiple values for E not Y and Z
these should be removed

Looks like it is showing as a Duex5 instead of a Duex2?

The opposite problems in these threads, unsure if its the same issue(s)

@Veti said in Duet-Wifi + Duex2 - short-to-ground reported by driver(s) 7 8 9:

M569 P7 R-1
M569 P8 R-1
M569 P9 R-1

I tested this and it works! Thank you!

I also changed the multiple settings for the Y and Z axis, this was no problem till yet -> but it is better to make it clean

@sebkritikel
You are right too! There is a DueX5 listet... I don´t know why ...

[Phaedrux]

Is this a new Duex2? When and where did you purchase it? It showing up as a duex5 is odd.

Can you try reflashing your firmware? Staying with 2.05.1 is fine.

[Phaedrux]

@CR3D I've been told this is likely caused by a bad connection underneath the SX1509b chip, which would certainly qualify for a warranty replacement.

[CR3D]

@Phaedrux ok thank you for this Information! i will contact Roland
